A joint venture with CMDC, Govt. of Chhattisgarh
Gem-grade corundum,
mined in Bastar.
Chhattisgarh Corundum Mines Limited works the Kuchnoor lease in Dantewada — ruby and sapphire rough for the gem trade, and industrial corundum for abrasives and refractories. Every lot leaves the mine with its origin on record.

The venture
A state partner and a trade partner, on one lease.
CCML was formed so that Chhattisgarh's corundum could be worked to gem standard rather than sold as raw abrasive. The Chhattisgarh Mineral Development Corporation brings the lease, statutory oversight and geological record. The private partner brings the sorting, cutting and buyer network that turns rough into a stone somebody wears.
- Operated under CMDC's mining and environmental compliance framework.
- Production, grading and dispatch recorded lot by lot.
- Local hiring and lapidary training in the Dantewada belt.

Leadership
Two signatures on every lot.
The venture answers to the state's mining administration and to the gem trade's working knowledge — the same balance the joint venture itself was built on.

What comes out of the ground
One crystal, two markets.
Corundum is pleochroic — turn the crystal and it shows you a different colour. The business works the same way. Clear, well-coloured material goes to the gem trade; everything else has real value as one of the hardest industrial minerals available.
Ruby rough
Chromium-coloured corundum from the Kuchnoor lease, sorted by colour, clarity and expected yield before it leaves site.
Star ruby
Silk-bearing material cut as cabochon, where fine rutile needles produce the six-ray asterism under a single light.
Sapphire & fancy corundum
Blue and off-colour corundum recovered alongside ruby, offered as rough or preformed parcels.
Graded parcels
Mixed lots made up to a buyer's brief — size range, colour band and treatment status stated up front.
Abrasive grade
Hardness 9 on the Mohs scale makes corundum a working abrasive for grinding wheels, blasting media and lapping compounds.
Refractory grade
High melting point and thermal stability for furnace linings, kiln furniture and high-temperature castables.
Ceramic feed
Alumina-rich feedstock for technical ceramics and advanced materials where wear resistance is the specification.
Precision finishing media
Closely sized fractions for surface finishing and polishing in engineering workshops.
Leases and prospects
Kuchnoor is working. Four more are being read.
Reserve and capacity figures follow the CMDC corundum project record.
Rough to certified stone
Six stages, and a paper trail at each one.
The order matters: a stone that skips grading cannot be certified, and a stone without certification cannot be sold as origin-known Indian ruby. This is the route every lot takes.
Prospecting
Pitting, trenching and sampling across the pegmatite and schist contacts.
Extraction
Small-scale, low-impact working sized to the 3.7 ha lease and its rated capacity.
Sorting
Gem-quality material separated from industrial feed at the pit head, then weighed in.
Lapidary
Preforming, cabbing and faceting — silk-bearing rough is cut to bring up the star.
Certification
Independent gemological reporting on species, treatment status and origin.
Sale
Direct supply and tendered lots, dispatched with the lot record attached.
Provenance
The lot number is the point.
Buyers in Jaipur, Surat and Bangkok are asked harder questions about origin every year. Because CCML sits inside a state corporation's compliance structure, a stone's route from pit to invoice is already documented. We pass that record on rather than keeping it.
Each dispatched lot carries its block, extraction month, weight in and weight out, grading notes and treatment declaration.
Community & land
Small lease, small footprint.
A 3.7 hectare working is not an open-cast operation and is not run like one. Overburden is stockpiled for backfill, water use stays within the sanctioned draw, and the site is worked in phases so disturbed ground is rehabilitated as the face moves.
Hiring, contracting and lapidary training are directed to the surrounding Dantewada villages first.
